Returns & Refunds

No product returns

Because these are laboratory research materials, we do not accept returns of unopened, opened, reconstituted or used vials. This does not prevent resolution of damaged, incorrect or lost shipments, cancellation before shipping, or remedies required by applicable law.

Damaged, incorrect or missing orders

• Report damage, a shipping error, or a missing package within 7 days of delivery with photos and your order number.
• Verified issues are resolved by replacement or reshipment at our discretion.
• Packages confirmed lost in transit are replaced or reshipped at no cost.

Cancellations

Orders can be cancelled at no cost any time before they are marked shipped. Contact us with your order number. Once an order has shipped, it cannot be cancelled.

Chargeback policy

We encourage customers to contact us first with any concern. Filing a chargeback without attempting resolution may result in permanent account suspension and forfeiture of any replacement offer.
